The Research Of System Dynamics In Strategic Environmental Assessment

As Carring out the Environmental Impact Assessment in our country, we also Actively promote the Strategic Environmental Assessment.But it Requested the Higher demands in Spatial and temporal scales. The method is currently a lack of domestic and international environment and the economy and society in the decision-making linked to reflect the results of the EIA planning methods, not from the system point of view of a dynamic, complex system of environmental impact factors. The accuracy of these deficiencies led to poor results are not satisfactory, the development of mitigation measures such as the lack of detail, therefore, it is necessary to develop a more comprehensive operational methods and models to address these problems. In the systematic analysis of the environmental impact of planning on the basis of the proposed system dynamics is applied in planning the specific environmental impact assessment methods and the idea of dynamic assessment.Yulin enrichment due to energy resources, as China's "Kuwait", is building a state-level energy and heavy chemical industry base, a strong impetus to regional economic development. At the same time, also become the West Yulin coal shipped East of the source of the hinterland of West-East Gas Pipeline, the West-East Power Transmission Project, which is a genuine continuation of the country and new energy production capacity in China market. Yulin as the development and utilization of energy resources, the vulnerability of the ecological environment was increasingly clear that the collapse of the main surface and groundwater decline, land desertification, rivers, wetlands shrink, natural disasters and environmental pollution. The existence of these environmental issues on the development and utilization of resources in Yulin and regional economic and social development of the depth of the sustainability constraints. Study on energy chemical industry base in northern Shaanxi environmentally sustainable development of science and rational development and utilization of regional energy resources is important. The text of the use of system dynamics (SD) method, system Yushenfu mining regional population, resources, economic and environmental impact assessment of the contents of the Planning, Environment and Yushenfu mining area of social development, resource exploration and development, environmental aspects of the development trend of the three the forecast. Simulation results show that the development of the next period, the region will be improved air quality, industrial wastewater and solid waste pollution heavy industry. Therefore, we proposed to increase the handling capacity of pollution to reduce emissions and increase investment in environmental protection, management responsibility for the implementation of the ecological environment and to strengthen environmental protection and supervision to improve environmental conditions in northern Shaanxi, the countermeasures and suggestions.
